The UC2845 is a popular integrated circuit from the Pulse Width Modulation (PWM) family of controllers. It is commonly used in voltage converters, such as switching power supplies, due to its current stabilisation and control properties.
- Supply voltage range: 7.6V to 30V
- Operating temperature range: -40°C to +85°C (industrial)
- Typical frequency: 52 kHz (for UC2845)
- Resting current: 11mA typical
- SOP8 housing SMD surface mount
- External capacitor and resistor allow frequency adjustment.
- Error amplifier with high gain.
- Output voltage stabilisation possible.
- Fast response to overloads.
- Adjustable current limitation thresholds.
- Possibility to externally disable the circuit by applying voltage to the corresponding pin.
- MOSFET transistor control output voltage: control voltage up to 1A.
- UVLO (Under Voltage Lockout): ensures that the circuit starts up correctly only when the appropriate supply voltage is applied.
- Adjustable pulse width (Duty Cycle): continuous or discontinuous operation possible, maximum pulse width up to 100%.
- Built-in soft-start, limits inrush current.

Swallowing Hazard – Small fastening components, such as screws, nuts, or washers, can pose a choking or swallowing hazard, especially for children. They should be stored in a place out of reach of children.
Spreading of Small Components – These components can pose a tripping or loss hazard during work. They should be stored in containers that prevent spillage.
